Why use a holder instead of tape or foam?
Ad hoc solutions using tape and foam have multiple issues. The net result is often a damaged or stuck battery.
Problems with Tape or Foam:
- They don't protect the delicate battery connection
- Tape or foam can shrink, causing the battery to fall out
- They can cause the battery to overheat
- Tape, especially, can fuse to the inside of the seat post
How to Remove the Poly Holder
Removing the holder requires pliers. Never use pliers on the battery itself.
- Grip the flat surface of the holder with pliers.
- While holding the pliers steady, rotate the seat post while gently pulling it away from the pliers.
- When the holder is about 1/2" (10-15mm) extracted, release the pliers.
- The holder and battery can now be removed by hand.
